Wetlands are vital water bodies, as crucial in a natural ecosystem as kidney in a human body. Apart from being highly productive as the habitat of birds, fishes and a variety of other aquatic life forms-micro-organisms. Wetlands provide other ecosystem services from maintaining the natural balance and for sustaining human livelihoods. Overall wetlands all over the country are exhibiting varying degrees of environmental degradation caused by encroachments, Eutrophication, siltation, urbanization and anthropogenic activities. There is also a misconception that wetlands are only wastelands. As a result, many precious wetlands have been converted to other uses all over in the world. Highly adaptable solutions must be found to permit development activities, including tourism,subsistence agriculture, and conservation of wildlife to be each given a fair share' of the one biome the wetland. This book provides an overview of the wetland study including flora, avifauna, management and restoration measures. It contains methodology of avifaunal survey, water quality analysis and WQI. It should be especially useful to those who are working in the field of wetland and environment conservation.
The Book 'Waste Water Irrigation' is an out-come of researches of about 5 years. Waste water is a great problem in developing countries like India. The waste water in India is generated through a variety of sources and its proper disposal is not an easy task. On the other hand lots of groundwater is wasted for irrigation, particularly for vegetables, which are mostly grown in the sub-urban area. Due to enormous pumping of water by the urban population in addition to the run off loss through vegetable irrigation, the water table occasionally falls abruptly in urban area, particularly during summers. In addition solanaceous vegetables are the most prominent food stuff, which is used round the year. Therefore, series of experiments were conducted through irrigating solanaceous vegetables by sewage. WQI of the sewage water and its suitability was also studied. The yield and nutrient analysis of the harvest was explored and compared to that of the crop irrigated by normal water. Satisfactory results were obtained. The book is supposed to be useful to all, involved in the researches of environment, may be from the discipline of Botany, Zoology, Geography, Biochemistry, Engineering etc.
